welcome to biodiesel for bands

Biodiesel is the name of a clean burning alternative fuel, produced from domestic, renewable resources. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.

Biodiesel is produced from any fat or oil such as soybean oil, through a refinery process called transesterification. This process is a reaction of the oil with an alcohol to remove the glycerin, which is a by-product of biodiesel production. Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to insure proper performance. Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the 1990 Clean Air Act Amendments. Biodiesel that meets ASTM D6751 and is legally registered with the Environmental Protection Agency is a legal motor fuel for sale and distribution. Raw vegetable oil cannot meet biodiesel fuel specifications, it is not registered with the EPA, and it is not a legal motor fuel.

For entities seeking to adopt a definition of biodiesel for purposes such as federal or state statute, state or national divisions of weights and measures, or for any other purpose, the official definition consistent with other federal and state laws and Original Equipment Manufacturer (OEM) guidelines is as follows:

Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats which conform to ASTM D6751 specifications for use in diesel engines. Biodiesel refers to the pure fuel before blending with diesel fuel. Biodiesel blends are denoted as, "BXX" with "XX" representing the percentage of biodiesel contained in the blend (ie: B20 is 20% biodiesel, 80% petroleum diesel).

Biodiesel is registered as a fuel and fuel additive with the Environmental Protection Agency (EPA) and meets clean diesel standards established by the California Air Resources Board (CARB). Neat (100 percent) biodiesel has been designated as an alternative fuel by the Department of Energy (DOE) and the US Department of Transportation (DOT).

The RFS program was created under the Energy Policy Act (EPAct) of 2005, and established the first renewable fuel volume mandate in the United States. Under the Energy Independence and Security Act (EISA) of 2007, the RFS program was expanded and now specifies four unique categories of renewable fuel: cellulosic biofuel, biomass-based diesel, advanced biofuel and total renewable fuel.

Biodiesel qualifies for both the biomass-based diesel category and the advanced biofuel category by achieving a life-cycle Green House Gas (GHG) emissions-reduction of at least 50 percent compared to baseline petroleum.

The RFS-2 requires a minimum of 1 billion gallons of biomass-based diesel be used annually between 2011 and 2022. It also requires the country use no less than 21 billion gallons of advanced biofuels by 2022. Biodiesel qualifies for compliance under both categories.

Biodiesel is the first fuel commercially produced nationwide that meets the U.S. EPA’s definition of an Advanced Biofuel.

Advanced biofuel is defined as a renewable fuel other than ethanol derived from cornstarch. The advanced biofuel category can apply to a variety of fuels, including biomass-based diesel, biogas, butanol or other alcohols and fuels derived from cellulosic biomass. Both advanced biofuel and biomass-based diesel must meet a life-cycle Green House Gas (GHG) emission-reduction threshold of 50 percent, and must be manufactured from feedstock meeting the definition of renewable biomass.

A fuel's life-cycle GHG emissions are defined as the aggregate emissions attributed to all components of fuel production and use, including feedstock production and distribution, fuel production, delivery, use and significant indirect emissions from land use change. The full life-cycle emissions level of a particular fuel is measured against a baseline fossil fuel in order to determine its GHG emissions reduction threshold.

Biodiesel can be used as a pure fuel or blended with petroleum in any percentage. B20 (a blend of 20 percent by volume biodiesel with 80 percent by volume petroleum diesel) has demonstrated significant environmental benefits with a minimum increase in cost for fleet operations and other consumers.

The National Biodiesel Board has released the following production volume

estimates for the US, per calendar year:

2013 -- 1.3 billion gallons

2012 -- 1.1 billion gallons

2011 -- 1.07 billion gallons

2010 -- 315 million gallons

2009 -- 545 million gallons

2008 -- 691 million gallons

2007 -- 500 million gallons

2006 -- 224 million gallons

2005 -- 112 million gallons

Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the Clean Air Act. The use of biodiesel in a conventional diesel engine not equipped with new diesel aftertreatment results in substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to emissions from diesel fuel. In addition, the exhaust emissions of sulfur oxides and sulfates (major components of acid rain) from biodiesel are essentially eliminated compared to higher sulfur diesel. Of the major exhaust pollutants, both unburned hydrocarbons and nitrogen oxides are ozone or smog forming precursors. The use of biodiesel in diesel engines not equipped with new diesel aftertreatment results in a substantial reduction of unburned hydrocarbons. Emissions of nitrogen oxides are either slightly reduced or slightly increased depending on the duty cycle of the engine and testing methods used. Based on engine testing, using the most stringent emissions testing protocols required by EPA for certification of fuels or fuel additives in the US, the overall ozone forming potential of the speciated hydrocarbon emissions from biodiesel was nearly 50 percent less than that measured for diesel fuel.  New Technology Diesel Engines (i.e. those with PM traps and SCR technology required for on-road applications in the US after 2010) reduce emissions of BOTH PM and NOx with B20 over 90% than 2004 model year and make NTDEs as clean or cleaner than either gasoline or natural gas fueled engines.  And use of low carbon B20 in NTDEs make them the clean, green technology of the future.

In general, the standard storage and handling procedures used for petroleum diesel can be used for biodiesel. The fuel should be stored in a clean, dry, dark environment. Acceptable storage tank materials include aluminum, steel, fluorinated polyethylene, fluorinated polypropylene and teflon. Copper, brass, lead, tin, and zinc should be avoided.

When reviewing the high costs associated with other alternative fuel systems, many fleet managers have determined biodiesel is their least-cost-strategy to comply with state and federal regulations. Use of biodiesel does not require major engine modifications. That means operators keep their fleets, their spare parts inventories, their refueling stations and their skilled mechanics. The only thing that changes is air quality.

Biodiesel can be operated in any diesel engine with little or no modification to the engine or the fuel system. Biodiesel has a solvent effect that may release deposits accumulated on tank walls and pipes from previous diesel fuel storage. The release of deposits may clog filters initially and precautions should be taken. Ensure that only fuel meeting the biodiesel specification is used.

A 1998 biodiesel lifecycle study, jointly sponsored by the US Department of Energy and the US Department of Agriculture, concluded biodiesel reduces net CO² emissions by 78 percent compared to petroleum diesel. This is due to biodiesel’s closed carbon cycle. The CO² released into the atmosphere when biodiesel is burned is recycled by growing plants, which are later processed into fuel. Is biodiesel safer than petroleum diesel? Scientific research confirms that biodiesel exhaust has a less harmful impact on human health than petroleum diesel fuel. Biodiesel emissions have decreased levels of polycyclic aromatic hydrocarbons (PAH) and nitrited PAH compounds that have been identified as potential cancer causing compounds. Test results indicate PAH compounds were reduced by 75 to 85 percent, with the exception of benzo(a)anthracene, which was reduced by roughly 50 percent. Targeted nPAH compounds were also reduced dramatically with biodiesel fuel, with 2-nitrofluorene and 1-nitropyrene reduced by 90 percent, and the rest of the nPAH compounds reduced to only trace levels.
